Level 1 Natural Selection
| Question | Answer |
|---|---|
| The change in a species or population over time | Evolution |
| All genes in a population | Gene Pool |
| The differential reproductive success of an organism that is best adapted to the environment | Natural Selection |
| The percentage of each gene in a population | Gene Frequency |
| The mathematical theory that a population is in genetic equilibrium or the gene frequency does not change unless one of the five tenets occur. The null hypothesis is that a population is in genetic equilibrium. | Hardy Weinberg Equilibrium |
| the allele frequency of the dominant allele A | p |
| the allele frequency of the recessive allele a | q |
| The gene frequency for homozygous dominant AA | q2 |
| The gene frequency for the homozygous recessive aa | p2 |
| The gene frequency for the heterozygous Aa | 2pq |
| The frequency of A or a in the population | allele frequency |
| A trait | adaptation |
| A change in the chromosome, gene, or DNA. Mutations can be silent, deadly, or beneficial. | mutation |
| A shift in a small population due to a random event. | Genetic drift |
| Mating where selection of mate does not depend on phenotype or genotype. | Random mating |
| The movement of genes into or out of a population. | Gene flow |
| The ability of an organism to survive and reproduce. | Fitness |
